50:1 that's 2.6 ounces of 2-stroke oil (preferably with fuel stabilizer) to one gallon of gas. I recommend using 89 octane gasoline for all small engines. It has little or no ethanol in it, as opposed to the 10% typical in 87 or 86 octane fuel. This will prevent a lot of fuel issues, especially if you are not using the tool daily or at least weekly.

is the kill switch on?check the spark plug it could have had the wire fall off in shipping

if you tighten the panel for the bar and chain too tight it pulls the bolts out slightly out of the chassis of the body. that is why it isnt oiling properly. i had a 235 and that is what happened to mine. what you could do is file down the raised plastic where the bolts enter the body and that might help.

You cannot just rotate the pump shaft and expect it to pump, it has to have a throw, this is done by an acentric groove in the nylon pump gear working on a steel pin in the pump cover, the bigger the throw the more oil is pumped, the biggest problem with the early model was the oil went down the side of the bar and not onto the chain, there was a later delivery/pick up pipe to solve this.

This model had many issues with oiling, there was a later reto fittable oil delivery tube to help this part no. 545227501.

You may have gotten some saw dust particles inside the oil resevoir that got sucked into the delivery tube, thus clogging up the oiler...you can drain the oil out of resevoir and run some seafoam thru the oil resevoir to see if you can get it unclogged

try using thinner oil

Get Chain lube for the chain oiler. Naturally, husqvarna recommends that you use "genuine husqvarna" oil for your mixture, I recommend a quality oil, doesn't have to be husky. Husqvarna recommends a 50:1 ratio, other manufacturers, of vertually all 2 cycle power equiptment use a 40:1 ratio. This mixture is slightly richer, but will not hurt your chainsaw. May produce a bit more smoke. Not sure what a 34 husky is...neither is Husqvarna, I visited the website and even tried to download a manual. Looked at every husky model, no 34.
